In particular, we will focus on the following aspects of this problem: the role of dual and multiple stellar populations in the star clusters and their groups; the long-term evolution of the stellar disk population, which inherited its properties from the decaying open star clusters populations; study of the properties of the distributions of stars in scattered star clusters. It is also planned to determine the coordinates of Ukrainian permanent GNSS stations in order to extend to the territory of Ukraine the implementation of the International Terrestrial Coordinate System (ITRF). It is planned to conduct a regular analysis of GNSS satellite observations at the set of Ukrainian permanent stations to estimate the coordinates of Ukrainian permanent stations itself and to estimate the values of zenith tropospheric refraction at these stations. popup.nrat_date 2024-12-09 Close
